Consider this class:

class ASillyClass {
  boolean aVariable;
  void aMethod() {
    aVariable = true;
  }
}

and its subclass which hides aVariable and overrides aMethod():

class ASillierClass extends ASillyClass {
  boolean aVariable;
  void aMethod() {
    aVariable = false;
    super.aMethod();
    System.out.println(aVariable);
    System.out.println(super.aVariable);
  }
}
